Attitudes towards uncertainty have been indicated to be highly context-dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2939 subjects in 30 countries measuring uncertainty attitudes through incentivized measures as...

We obtain rich measures of risk preferences of poor farmers in Vietnam, and estimate structural models that capture risk preferences over different probability levels and across different domains (gains and losses). The results break radically with the previous literature on risk preferences, in...

We looked at risk and ambiguity attitudes among Ethiopian peasants in one of the poorest regions of the world and compared their attitudes to a standard Western university student sample elicited by the same decision task. Strong risk aversion and ambiguity aversion were found with the Ethiopian...

We investigated attitudes toward positionality among rural farmers in Northern Ethiopia, using a tailored survey experiment. On average, we found positional concerns neither in income per se nor in income from aid projects among the farmers. These results support the claim that positional...

Previous research suggests a lower degree of positional concerns among people from poor countries. Yet the evidence is limited and most often builds on the assumption that people's reference groups are the same across all individuals. We conduct a survey experiment in urban Ethiopia that is...

Land conflicts in developing countries are costly. An important policy goal is to create respect for borders. This often involves mandatory, expensive interventions. We propose a new policy design, which in theory promotes neighborly relations at low cost. A salient feature is the option to...

We measure risk attitudes in 30 different countries in a controlled, incentivized experiment (N = 3025). At the macroeconomic level, we find a strong and highly significant negative correlation between the risk tolerance of a country and income per capita. This gives rise to a paradox, seen that...

Risk aversion has generally been found to decrease in income or wealth. This may lead one to expect that poor countries will be more risk averse than rich countries. Recent comparative findings with students, however, suggest the opposite, giving rise to a riskincome paradox. We test this...

We examine situations in which a decision maker decides for another person as well as herself under conditions of payoff equality, and compare such decisions under responsibility to individual decisions. Estimating a structural model we find that responsibility leaves utility curvature...

Prospect theory (PT) is the dominant descriptive theory of decision making under risk today. For the modeling of choices, PT relies on a psychologically founded separation of risk attitudes into attitudes towards outcomes, captured in a value function; and attitudes towards probabilities,...
